Key Features

Triple pole switching

Benefits

• Compact 54 mm switch width supports space-conscious panel layouts.
• Bottom fitting installation suits distribution assemblies and panel mounting.
• Safe on-load connection and disconnection supports controlled isolation.
• Large windows with testing holes assist viewing and test access.
• Padlocking and sealing facility supports isolation control during maintenance.

Technical Summary

NH fuse switch disconnector, size 000, triple pole, 125 A rated current, 690 VAC rated operational voltage, 1000 V insulation voltage, 6 kV impulse withstand voltage, IP30 protection, frame clamp terminals 2.5–50 mm², bottom fitting installation. Rated conditional short-circuit current up to 80 kA with fuse links at AC 500 V and AC 690 V applications as stated in the datasheet; DC conditional short-circuit rating listed as 25 kA at 250 VDC.

Installation Notes

Designed for bottom fitting / panel installation. DIN-rail adapter is available as an accessory for DIN EN 60715 rails 35 x 7.5 mm and 35 x 15 mm. For distribution units with central cover, matching covers are used to maintain a uniform profile in height and length.

Efficiency

Power dissipation is stated as 8 W at 100 A load and 13 W at 125 A load without NH fuse-links. Max. power dissipation of fuse links is stated as 9 W.
